“…However, in practice, the country-specific tariff is not always available, and in such scenarios, tariffs derived from other countries can be adopted. Literature indicates that different cultures could influence the derived utility scores 31,32. Previous studies regarding the EQ-5D-3L instrument and its tariffs showed that it would be better to choose tariffs with similar cultural backgrounds 26,27,33.…”

ObjectiveThe objective of this study was to compare the differences in the five-level EuroQol-5 dimensions (EQ-5D-5L) health state utility scores derived from Chinese, Japanese, Korean, and UK tariffs.MethodsSix hundred and twenty-one breast cancer patients were invited for a face-to-face interview in Qingdao Municipal Hospital, China. EQ-5D-5L was scored using tariffs from China, Japan, Korea, and the UK. The null hypothesis of normal distribution of the EQ-5D-5L utility score was tested by the Shapiro–Wilk test. Nonparametric Friedman test and Wilcoxon signed-rank test were used to determine the difference among the four tariffs. The intraclass correlation coefficients (ICCs) and Bland–Altman plots were used to study the agreement among the four EQ-5D-5L scores. Known-groups validity was studied using a regression framework.ResultsThere were 608 participants in the final analysis, with a mean ± standard deviation (SD) age of 48.0±9.6 years. EQ-5D-5L utility scores were non-normally distributed. The means (median) ± SD of EQ-5D-5L utilities derived from Chinese, Japanese, Korean, and UK tariffs were 0.828 (0.879) ±0.184, 0.802 (0.823) ±0.164, 0.831 (0.829) ±0.137, and 0.838 (0.866) ±0.154, respectively. Among pairwise comparisons, the difference of median EQ-5D-5L utility scores was only insignificant between Chinese and UK tariffs. Excellent agreements (with ICCs >0.9) were found among the four tariffs albeit the limits of agreement between each pair of tariffs were wide. Known-groups validity was supported.ConclusionAlthough four country-specific EQ-5D-5L tariffs have shown an overall high level of correlation and agreement, none of them could be regarded as interchangeable. The higher correlation and agreement between Chinese and UK tariffs may be due to the similar functions that were used in the tariff development. In the absence of Chinese-specific tariff, the UK tariff is the second-best option to be applied in the Chinese population. Results of this study further contribute to the explanation of variations among country-specific tariffs.

“…Details of patients characteristics and methods of data collection appear in the sources cited. Some of the patients in the original stroke study had been recruited outside the UK but their records were omitted from this analysis, as there are grounds for believing that EQ-5D responses vary geographically [21]. The other studies had been conducted with UK subjects only.…”

Does the correspondence between EQ-5D health state description and VAS score vary by medical condition?

Health and Quality of Life Outcomes

BackgroundThe EQ-5D health-related quality of life instrument comprises a health state classification (health problems by severity in five domains), followed by an evaluation using a visual analogue scale (VAS). Despite the EQ-5D’s use in health technology assessment and as a patient-reported outcome measure (PROM), the correspondence between the two parts of the instrument remains ill-understood. In this paper, we consider whether the association between health state classification and VAS score might vary by medical condition.MethodsEQ-5D data collected for studies of patients in four different clinical conditions or circumstances (stroke, low back pain, colposcopic investigation or cytological surveillance) were pooled to generate a sample of 3,851 patient records. VAS scores were regressed on reported problem severities, with the inclusion of intercept and slope dummy variables specific to condition.ResultsThe regression model achieved a goodness-of-fit of 0.54. Given its structure and the significance of the coefficients, the proportion of VAS scores which differed by condition for the same health state varied between 33.3 and 88.5 per cent of possible states.ConclusionsMany of the patients with different medical conditions or in receipt of different interventions recorded different VAS valuations, in spite of ostensibly being in the same EQ-5D-defined health states. By implication, it is probable that the same state-to-state change would by valued differently by patients experiencing different conditions.

“…Linear regression analysis showed that gross domestic product explained 67% of the EQ visual analogue scale (p = 0.02) when outliers were excluded and 29% when the outliers were included; per-capita health expenditure explained 26% of the mean visual analogue scale (p = 0.03). Finally, in a preliminary study of the relationships between national culture and EQ-5D value sets, power distance (that is, a society in which people expect and desire inequalities among themselves) and individualism were found to have moderate and strong correlations with pain and discomfort, and anxiety and depression 22 .…”

“…Differences in age, sex, standard of living, and preferences by health state in the general population of various countries can potentially contribute to cultural differences in a model 22,23 . For example, a French valuation study found that French respondents weighted problems in the mobility, self-care, and usual activity parameters more heavily than did U.K. respondents 24 .…”
